I’m sure if you’ve been to a southern family reunion anytime in your lifetime, you’ve most likely noticed the squash casserole dishes that always appear. And then disappear just as quickly.

It is just one of those recipes that is a foolproof crowd pleaser.

    I hate to ask this question because I see so many people ask questions that are covered in the text, but when do you add the Ritz crackers?

    • 6

      Thanks so much, Pat for catching that. You add the Ritz crackers right before popping the squash casserole into the oven. I’ve updated the recipe to include that. I really appreciate you!!! xoxo

  6. 7

    You don’t add the butter to the crackers before you top the casserole?

    Love comfort food casseroles! Need to get some squash!

    oh my heavens! I have never seen such a recipe…it looks amazing. I can see why it would be a staple! i think we Northerners need to adopt it as a new staple also.

    Would this recipe work fine with zucchini too (instead of yellow squash)? Just thinking ahead to the abundance of zucchini I will have in my summer garden & this recipe sounds like it could be added to my good list of zucchini recipes :)

    I made the squash casserole for Easter and it was amazing. My daughter is a vegetarian so I can never have enough of these winners in my recipe file. Thanks

    I made this casserole last weekend, and my boyfriend loves it. In fact when I pulled it out of the refrigerator to warm up the leftovers, I found out he had been eating it for lunch a day or so later :). I have more squash so guess what we are having again this evening? Thank you for this delicious recipe!

  12. 14

    I would love to make this dish for my boyfriend. It looks really delicious and seems easy.
    I am not exactly a very experienced cook and need to know approximately how many squash would make 4 cups?


  13. 15

    Could you use mozzarella cheese instead of cheddar?

    You have 2 tablespoons of butter listed twice in your ingredients. Is the second 2 Tablespoons of butter added to the crushed Ritz cracker for the topping?

    • 17

      Hi Shirley. You’ll use a total of 4 tablespoons of butter for this recipe.

      Shirley Carnley says:

      That really didn’t answer my question. Is two of the tablespoons of butter mixed with the Ritz crackers as a topping?, Or are all four tablespoons of buter “IN” the casserole mixture?

    Shirley Carnley says:

    It still isn’t clear about the 4 tablespoons of butter in your recipe. Because it is listed separatly, I am going to use the second 2 tablespoon to the Ritz cracker topping and hope for the best. I hope I don’t ruin it, because the recipe sounds delicious.

      Shirley, the recipe states that you use 2 Tbsp butter to saute the squash and onions in step 1. In step 3, you melt the remaining 2 Tbsp butter and add that to the cooked squash mixture before you put it in a casserole dish.

    I just made the squash casserole for Thanksgiving. I, of course, had to try it out with a taste test. It is very delicious. Thanks Robyn.

    Hello Robyn,

    I’ve been looking every where to find my Grandmothers recipe and I do believe yours is the closest I’ve yet to find. Thanks for that. :) Just one question though…I’m almost positive she used cornbread dressing (instead of Ritz’s) mixed in at the time you bake. Does that sound like that would work?

    Looking forward to hearing your opinion.

    Thanks again! ;)

      Hi Stacey,
      I’ve never made my squash casserole that way. Do let us know if you make it that way in case others are interested in that version.

      During my search for Squash Casserole recipes, I found a recipe on Campbell’s website using Pepperidge Farm cornbread stuffing and cream of chicken soup. Hope this helps.

    only 4 cups of squash slices will feed 12 servings of this casserole. It smells delicious cooking but was surprised that it looks like servings will be extremely small? How big a serving are you proposing in your recipe?
